NASA - Mission Overview - About IBEX
October 3, 2008
 


The Interstellar Boundary Explorer (IBEX) is a new NASA mission launching in Oct. 2008, which will study the interaction between the solar wind and the material beyond our solar system called the interstellar medium. The solar wind flowing out of the sun inflates a bubble that we call the heliosphere. IBEX's job is to study the boundaries of our solar system and tell us how the heliosphere is able to do the important job of protecting us here on Earth as well as astronauts in space from galactic cosmic rays.
